Phaseliforma laxa
No picture of Phaseliforma laxa was found. Wikidata, iDigBio and Smithsonian Open Access were searched and had none. Wikipedia did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Phaseliforma laxa, or no answer at all. This entry cannot say which.
On record
Recorded, not inferred- Sits inside
- PhaseliformaPBDB
Time the record covers
At least 28 million years on record.
The record covers at least 89.8 Mya to 61.66 Mya. No occurrence read is dated outside 93.9 Mya to 59.24 Mya.
31 occurrences of Phaseliforma laxa on record, most of them in the Paleocene. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.
When
31 occurrences- Late Cretaceous39%
- Paleocene61%
These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The named rock units Phaseliforma laxa has been recovered from, largest first. Drawn where the rock is now, not where it formed. 8 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records 30 sites for Phaseliforma laxa, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Each of the 31 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
